Thank you for your feedback. That's interesting. I added the field guide on the game's page yesterday and I think that may have overcomplicated the first two rooms.
If I may ask, were you looking for all three signs in the first and second room? In the first room, you only need to worry about the wet patches. I've actually just updated the game description to make that clearer for new players so they don't overthink the start!
Congrats on getting to the end and glad you liked the cutscene! Thank you again for playing.
